The standard version - the one we know since 2016- still apply's to the "normal" AT that are still produced, but the Adventure Sport is more of a Adventure tourer with some additions. Most notable...It has the Touring screen. Bigger tank. Slightly beefed up suspension, raising it by a couple of millimeters. Ride by wire. Heated grips. Colour scheme, of course. New bash plate and crash bars included.
It does seem that these particular Adventure Road, new colour scheme bikes are just that... only new colour scheme bikes. Its part of the standard AT versions that are still manufactured.
